KL3454, KS3454, KL3458, KS3458 | 4-, 8-channel analog input terminals 4…20 mA

The KL3454 and KL3458 analog input terminals process signals in the range between 4 and 20 mA. The current is digitised to a resolution of 12 bits and is transmitted, in an electrically isolated form, to the higher-level automation device. In the KL3454 Bus Terminal, the four inputs are 2-wire versions and have a common ground potential. The 24 V power contact is connected to the terminal, in order to enable the connection of 2-wire sensors without external supply. The KL3458 variant combines eight channels in one housing and is particularly suitable for space-saving installation in control cabinets. The use of single conductor connection technology enables the connection of multi-channel sensor technology with minimum space requirements. In the KL3454 and KL3458, the power contacts are connected through. The reference ground for all inputs is the 0 V power contact. Overload is detected in both variants. The terminal status is relayed to the controller via the K-bus. The run LEDs indicate the data exchange with the Bus Coupler, the error LEDs overload or wire breakage.
